The key events of the Air India crash investigation

The preliminary report on the Air India crash, which killed 260 people, revealed that the fuel cutoff switches for the engines were switched from run to off almost simultaneously seconds after takeoff. This deprived the engines of fuel.

The timeline below shows the key events of the investigation so far:

JUNE 12

Air India Boeing 787 Dreamliner headed for London crashed shortly after takeoff in Ahmedabad, killing all 242 passengers on board except one.

JUNE 13

India's Aircraft Accident Investigation Bureau launches an investigation in the deadliest aircraft crash of the past decade.

The team includes a representative from the U.S. National Transportation Safety Board, a flight traffic controller, and an aviation medicine specialist.

Boeing 787 jets are equipped with two GE recorders. One is installed in the front of the jet and the other at the back. Both aircraft have a cockpit data recorder as well as a voice recorder.

A black box is recovered on the roof of a nearby building.

JUNE 16

The second blackbox unit was recovered from the debris on the crash site.

JUNE 24

Indian Air Force aircraft transported the two black boxes separately from Ahmedabad, India to a lab at AAIB in Delhi.

The team, led by the AAIB Director General and technical members of AAIB as well as the NTSB, began the data extraction in the evening.

JUNE 25

The data from the memory module of the black box unit at the front end of the aircraft was successfully downloaded.

In a report from 2014, the NTSB stated that the forward recorder has an independent power supply which provides backup power for the device for approximately 10 minutes in the event of a plane's loss of power.

JULY 12

The preliminary report indicated that no action was recommended to Boeing or GE, indicating that a fault with the aircraft or engine is unlikely.

The report said that one pilot could be heard asking the other pilot on the cockpit recording why he had cut off the gas. The report stated that "the other pilot replied that he had not done so."

The crash report did not specify which flight captain made the remarks and which first officer. Nor did it identify which pilot sent out "Mayday Mayday Mayday" before the crash.

The final report should be ready within one year after the accident. Reporting by Abhijith Gaapavaram, New Delhi. Editing by Jamie Freed
